Pico GameBoy printer

Based on the original webserver for the PI Pico repo: https://github.com/maxnet/pico-webserver

Webserver example that came with TinyUSB slightly modified to run on a Raspberry Pi Pico. Lets the Pico pretend to be a USB Ethernet device. Runs the webinterface at http://192.168.7.1/

Schematics

You will need a Raspberry Pi, 1/2 of the game boy link cable and a four-channel 5v to 3.3v level shifter. Connect parts as shown:

This is the example of the ready-to-use device:

Build dependencies

On Debian:

sudo apt install git build-essential cmake gcc-arm-none-eabi

Your Linux distribution does need to provide a recent CMake (3.13+). If not, compile CMake from source first.

On Windows:

Install ARM GCC compiler: https://developer.arm.com/downloads/-/gnu-rm
Install MSYS
Install CMake

Then use this command

cmake .. -G "MSYS Makefiles"

instead of

cmake ..

in the build instructions below.

Build instructions

git clone --depth 1 https://github.com/untoxa/pico-gb-printer
cd pico-gb-printer
git submodule update --init
mkdir -p build
cd build
cmake ..
make

Copy the resulting pico_gb_printer.uf2 file to the Pi Pico mass storage device manually. Webserver will be available at http://192.168.7.1/
